IMPROVEM ENT IN CULTIVATING-PLOWS.

Specification forming part of Letters Patent-No. 28,487, dated Mey 29, 1860.

To all whom it may concern: Be it known that I, ALLEN HUGHES, of Gratiot, in the countyr -of Licking and State ot Ohio,,ha,ve invented a new and useful Improvement in 'Shovel-Flows; and I do hereby de- Aclare that the following is a full, clear, and exact description thereof, reference being had to the'accompanying drawings, forming a part of thisispcci-tication, in which- 1 Figurel represents a perspective view of my improved cultivating-plow; Fig. 2, a plan view of a portion of the frame of the same, showing the-partsin two positions.

Similar letters of reference indicate corresponding parts in both figures.

The object of this invention is to connect fthe Shanks carrying the shovels to. the frame or beams of the cultivator in such a manner that the same are not weakened by'drilling holes through them, as in the common method also, to attach two or a gang of shovels to the frame of the cultivator in such a manner that lthe same may be adjusted and set at different distances apart, according as it is desired to plant the crops.' p

'The invention consists' in jointing the front ends of the Shanks to the beams of the cultiv'ator in such a. manner that the -shovels may be raised or depressed, and in xing the shov-l els in the shanks carrying them rigidly to the beams by sector-bars` having pins passing through them and through the beams, as will be' hereinafter describedand represented.

1t further consists, in conjunction with the /mode ofattaching the shovel-Shanks to the i beams, in making these 'beams adjustable in the centralwbeam, so that they may be contracted oriextended, and with them the shovels attachedv tothem, as will be hereinafter del scribed. t To enable thoseskilled inthe art to fully. understand my invention, I .will proceed todescribe its construction and operation.

f In the drawings, A representsjthe central beam, to the frontpart' of which is attached the ends of handles B B, which proceed back, and are supported and strengthened by bracerod C and -curviedlarmsl) D, which latter conneet these handl'eswith the rear., end of the beam. -flhrough the central beam., A, at .two

points, are cut mortises, through which pass transverse extension-bars E E `E E, that are attached to two short beams, F F, that are `parallel with the central beam, A. The bars E are connected at their ends together with metal straps a a a u, that serve to keep these bars well stayed, and by bolts b b4 they are rigdlyattached to the eentralbeam, A. These bars, with their beams, are capable 'of being extended or contracted by removing the pins b b. They may then be fixed to the central beam, A, as before stated.

To the central beam, as well as to the two` side beams, F F, is attached thecurved shovelstandards Gr Gr' G in the following novel'man# ner. t

dd d are perpendicular slotted portions'prd jectiug down from the beams that are screwed at suitablepeints--tothethree --besmsand ecured by nuts, as representedtin the drawings, and between the slots in the ends of these portions are bolted the `ends of the curved standards G-"G G. From these points or joints i the standards proceed back, are curved, as represented, and receive the shovels c c c on their lower ends. At ornear the rear part ot' the straight portions of these standard-bars they are attached to the beams againbyc'urved upright portions J J J, having perforations through them, which pass up through suitable holes cut through the beams and receive pins or bolts e e e, that pass transversely through the beams and through one of the perforations in these plates.' These curved or sector plates J are of a sueient length to admit' of any required adjustment being given to the shovels for running deeper or shallower into the earth. The shovels may be set as represented inthe drawings, one being behind the other, or in any other desirable wa'y.

.From this description ,1t will be Vseen that my cultivator is capable of being adjusted laterally or vertically--laterallyl for working the earth in rows of any -desirable width (by removing the middle shovel the rows may be made still wider) and vertically for working at any depth required.

TheA most important object in the sectorplates J is to .dispense with the `holes usually made in the shank or standard-bar, that weaken vthis bar so much that; it is yery liable] to break Where these holes occur. By' the einployment of such projections greater facility oi' adjustment is obtained, While the shank or shovel-bar is not reqnired.

The operation of this class of machinery for the cultivation of corn crops is too well under- Haviiig thus described xnyinventioinv'vhatl claim, and desire to secure by Letters Patent, 1s

The shovel cult-ivator herein described,'capa ble of'both a lateral and avertical-adjustment,

when madeV in the manner and by the con bined arrangement herein described and repstood to need further explanation. It is only resented.

necessary to'say that these adjustments are very important; where crops are sown irregular, and require to be frequently made. This machine willanswer the requirements and save much hard labor.
